The rigid brake lines form the hydraulic connection between the master cylinder and the vehicle's wheel braking components. When the brake pedal is pressed, hydraulic pressure generated by the master cylinder travels through these pipes, allowing the braking system to apply the brakes at each wheel.

Over decades of use, original steel brake pipes can suffer from corrosion, external damage, seized unions or internal contamination. Because brake lines carry pressurised brake fluid and form a safety-critical part of the braking system, pipes showing significant deterioration should be replaced rather than relied upon indefinitely.

This kit provides the principal rigid brake pipes required to renew the system using correctly specified replacement lines.

What This Product Does:
The rigid brake pipes carry hydraulic brake fluid under pressure throughout the braking system.

The kit is designed to:

• Transfer hydraulic pressure from the master cylinder.
• Deliver brake fluid to the front and rear braking circuits.
• Maintain a sealed hydraulic connection between braking components.
• Support simultaneous and predictable braking operation.
• Replace corroded or damaged original steel brake lines.
• Restore the integrity of an ageing hydraulic braking system.
• Provide replacement pipes for a full brake-system restoration.
• Help eliminate leaks caused by deteriorated brake pipes.
• Restore correctly routed hydraulic connections.
• Support safe and consistent brake operation.

Because the vehicle uses a dual-circuit system, the hydraulic system is divided into separate circuits to provide additional braking-system redundancy compared with an earlier single-circuit arrangement.

Symptoms Of Wear Or Failure:
Possible signs of brake line deterioration include:

• Visible rust on the steel pipes.
• Heavy corrosion or pitting.
• Flaking metal around the brake pipe.
• Dampness around pipe unions.
• Brake fluid visible on the pipe surface.
• Brake fluid dripping beneath the vehicle.
• Falling brake fluid reservoir level.
• Soft or spongy brake pedal.
• Brake pedal travelling farther than normal.
• Reduced braking performance.
• Brake pedal slowly sinking under constant pressure.
• Uneven braking.
• Brake warning light illuminating where applicable.
• Corroded or seized pipe unions.
• Crushed or kinked brake lines.
• Abrasion where pipes contact the body or other components.
• Damage resulting from previous repairs or underbody impact.

Corrosion gradually reduces the thickness and strength of a steel pipe. A line that appears only moderately rusty externally may be substantially weakened if corrosion is deep or concentrated around clips, bends and unions.

Replacing deteriorated brake lines helps restore:

• Hydraulic-system integrity.
• Reliable brake-fluid containment.
• Consistent braking pressure.
• Correct pedal feel.
• Reliable operation of both brake circuits.
• Long-term braking-system safety.
• Confidence during a complete restoration.
